Who actually do quite a bit of good with it:
"We should start by noting that Catholic charity work is extensive and widely considered a crucial part of the nation’s social safety net. By itself, Catholic Charities USA, has more than 2,500 local agencies that serve 10 million people annually, said Mary L. Gautier, a senior research associate at the Center for Applied Research in the Apostolate, an institute at Georgetown University that studies the church."
"Meanwhile, Catholic News Service has noted a few other Catholic organizations that made the Chronicle’s annual 400 list, including Father Flanagan Boys Home and Covenant House. This excludes Catholic universities, which mainly provide higher education; hospitals, which are categorized separately from social services; and groups that focus on overseas work."

Considering they put out close to 4 billion every year in charity, it's hard to argue they don't help the impoverished.
